FIREPROOF WINDOW.

i Specification of Letters Patent.

Patented March 27, 1906.

Application filed December 12,1905. Serial No. 291,443.

To all whom it may concern.-

Be it known that I, WILLIAM HENRY MIL- LER, a citizen of the UnitedStates, residin at Galveston, in the county of Galveston and State ofTexas, have invented certain new and useful Improvements in-FireproofWindows; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to improvements in window construction, and it ismore particularly an improvement upon the construction disclosed in myapplication for United States patent filed September 20, 1905, SerialNo. 279,317.

The object of the invention is to simplify the construction so that thesame can be made at a great reduction in cost.

Another object is to provide means for automatically closing the lowersash when subjected to a predetermined temperature, said sash beingprevented from dropping with such violence as to injure it.

WVith the above and other objects in view the invention consists ofcertain novel features of construction and combination of parts whichwill be hereinafter more fully described, and pointed out in the claims.

In the accompan 'ng drawings I have shown the preferred orm of myinvention.

In said drawings, Figure 1 is a perspective view of a window frame andsashes constructed in accordance with my invention. Fig. 2 is a verticalsection therethrough. Fig. 3 is a horizontal section-through the lowersash and the adjoining portions of the frame. Fig. 4 is a frontelevation ofa portion of the top rail of the upper sash and showingindotted lines the position of the weight-holding receptacle therein- Fig.5 is asection on line :0 112, Fig. 4. Fig. 6 is a vertical sectionthrough the lower portion of the Windowframe and showing in elevationthe closure in positiomover the weight-receiving aperture. Fig. 7 is adetail view of said closure. Fig. 8 is a perspective view of theadjoining ends of the fixed and removable section of one of theparting-strips, a portion of the fixed section being broken away to showthe end of the removable section therein. Fig. 9 is a perspective viewof a portion of the removable section of the parting-strip looking atthe same from inside of the window-strip and showing the means fordetachably secur- 6-is held within the ing said parting-strip to thewindow-frame. Fig. 10 is a perspect1ve.view of a portion of thewindow-frame looking at the same from the inside thereof and showin themanner of permanently fastening the cad-strip to said frame. Fig. 11 isa section throu h a modified form of bead-stri and the ad oining portionof the window-flame. Fig. 12 is a detail view of a nut adapted to beused in connection with the fastening means shown a in Fig. 9; and Fig.13 is a section on line y y,

Fig. 2.

Referring to the fi ures by numerals of reference, 1 1 are the si es ofthe window-frame, and 2 and 3 are the head and sill, respectively. allof said parts being connected at their ends by rivets 4, so that asolidlyconstructed frame is produced after the manner described in myapplication, hereinbefore mentioned.

he inner or adjoining faces of the sides of: the window-frame areprovided with channels 5, and in each of these channels is disposed aparting-strip formed of two sections 6 and 7, res ectively, each of saidstrips being substantially U-shaped. .The upper section channel by meansofbolts 8, which screw into nuts 9, soldered or otherwise permanentlyfastened inside the side 1 I of the window-frame. The u per sections 6of the arting-strips extend ownward to a point 0 ose to the center ofthe window-frame and receive the tapered ends 10 of the lower members 7of the parting-strips. It is obvious that the u per ends of thesemembers 7 are held secure y in place, because they project into theupper members.6. The lower portions of the members, however, aredetachably fastened bymeans of bolts 11, which extend throughkeyhole-slots 12 in the inner walls of the channels 5 and engage nuts13, which normally overlap and are soldered to the edges of thecontracted portions of slots 12, and therefore prevent the withdrawal ofbolts 11. Instead of providing an ordinary form of nut upon the bolts11, I can use a nut 14, such as shown in Fig. 12, and which has itsopposite edges grooved, as shown at 15, to receive the edges of thecontracted portion of each slot 12. With this arrangement the nut'willbe held against rotating, and loosening of the bolt is practicallyprevented.

Narrow channels 16 are formed within the adjoining faces of the sides 1for the reception of bead-stri s 17. The beads of these strips may be 0yindrical, as shown in Figs. 3

it o

and 10, or, if preferred, can be angular, as shown in Fig. 11 at 18. Ineither caseeach bead-strip is formed of an upper section 19 and a lowersection 20, the upper section be ing immovably fastened in place byslitting the walls of the channel, as well as that portion of the striptherebetween, and then folding back the walls and strip, as shown at 21in Fig. 10. The upper sections of the beadstrips are thus permanentlysecured without the use of solder or other like means.

The lower portions 20 of the bead-strips are adapted to he forced intothe channels 16 and can be detachably held by means of bolts 22, whichscrew through the lower portions of the channels 16 and the stripstherein, said screws being inserted into the sides 1 of the frame fromthe inside faces thereof, as shown particularly in Fig. 3. Apartitioni28 is located within one of the sides 1 and is riveted orotherwise fastened to one of the walls of said side. Another partition24 is fastened within each side 1 by means of the bolts 8. It willtherefore be seen that one partition is located within one of the sides1, so as to divide said side into two compartments 25 and 25, while twopartitions 23 and 24, respec tively, are disposed within the outer side1 and divide said side into three compartments 25, and 27. Thepartitions 24 are only employed where the window-frames are very long,and long balance-chainsare necessarily employed in order that weigi'itsmaybe conveniently coi'mectcd to the b alarms-chains, openings 28 areformed. in the s es 1 and are of sufficient size to permit an ordinarybalance-weight to be inserted ther rough. Each of these openings ilocated between. one of the pa t ing-strips and bead strips and isadapted to he closed by means of a plate 29, having side flanges 30,which are inserted into the openand lit snugly against the sidesthpreof. One end 31 of the plateill is inserted iinder the upper edge ofthe opening 28, while the opposite end of plat- 9 overlaps the lower ofthe opening and has an aperture a r the reception of a M hiring-boltlloth sashes arc construe s after the man:

nor described in my former application, the only exception being thatthe upper sash has a weight-receptaele 35 in its upper rail, whicsecured in place by the same rivets which fasten the parts of the upperrail together. This re ieptacle is trougleshaped, as shown particularlyby dotted lines in Fig. 4, and is adapted to contain a desired quantityof shot 37, adapted to escape through an openimg- 38, which, however, isnormally covered by a fusible closure 39, having a stem extending upwardtherefrom and above the upper rail of the sash. This upper sash issupported in the ordinary manner by means of balance-weights 41, (shownby dotted lines in Fig. 3,) said weights being; conerases nected to thesash by means of chains. (Not shown.) T he lower sash 42 has a rod 43extendingvertically through the center thereof, and where a mullion-baris employed this rod extends therethrou h, as shown in Fig. 2, and whereno mullionar is used the rod is located adjacent one face of the glass.In both instances the lower end of the rod is secure-d to the bottom ofthe lower sash by a fusible tip 44, while the upper end of the rod,which projects above the ower sash 42, has an eye 45, to which issecured one end of a chain 46. This chain extends through the head 2 ofthe frame and over a'pulley 47, mounted on brackets 48 within said head,and from this pulley it extends over a second pulley 49 within said headand downward into the compartment 27, where it is con nected to a smallweight 50.

Ordinary balance-weights 51 (shown by dotted lines in Fig. 3) areconnected to the lower sash by means of chains 52, and the we'ghts 50and 51 combined serve to balance the lower sash and support it in anyposition to which it may be moved.

The chains 52 are preferably connected to the sashes in the manner shownin Fig. 3, where it will be noticed that the end link of each chain 52is engaged by the stem of a bolt 53, the head of which is located withinthe side rails of the sash and is soldered or otherwise fixedlyconnected thereto, while a nut 54 is disposed on the bolt and serves toclamp the chain-link against the side of the sash.

The partitions and 24 serve to prevent the weights and their chains frombecoming entangled, and while the partition 23 is al ways employed thepartition 24 may, as heretofore stated, be dispensed with, except wherethe balance-chains are of considerable length.

in windows of extremely large size the weights of course can be insertedthrough openings 28, and in such cases it would be necessary to placethem in the sides 1 before the masonry has been built around them.

it is to be understood that under ordinary conditions the sashes areperfectly balanced by their respective weights and can be supported bythem in any desired position with in the frame.

Should the sashes while open be subjected to a predetermined degree oftemperature, the fusible closure 39 will be melted so as to uncover theopening 38, and the shot 37 will escape therethroug i and reduce theweight of the upper sash, so that the balances 41 will promptly raisesaid sash into closed position. will be melted and release the rod 43from the lower sash 42. Said sash will therefore be relieved. of the support given by weight 50, and as the remaining weights 51 are notsullicient in themselves to support the sash 42 At the same time thefusible tip 44 said sash will move downward into closed position, butwill be prevented from dropping violently, because it Will be retardedby the weights 51. r It will of course be understood that variouschanges in the form and minor detalls may be resorted to Withoutdeparting from the scope or spirit of the invention.

What I claim is 1. The combination with a sheet-metal Window-framehaving channels in the sides thereof and slots in the Walls of thechannels, each having a contracted portion of a sec tional parting-stripin each channel, means for permanently securing one of the sectionsWithin the channel, the second section having one endprojecting into thepermanently-secured section, and means engaging-the-Walls of the slotsfor detachablysecuring said second section within the channel.

2. The combination with a sheet-metal Window-frame having channels'inthe sides thereof and slots'in the Walls of the channels, each having acontracted portion of a sectional parting-strip in each channel, meansfor permanently securing one of the sections within the channel, thesecond section having one end projecting into the permanentlysecuredsection, a grooved device slidably mounted Within the contractedportionof the slot, and means engaging said device for detachably securing thesecond section Within the channel.

3. The combination window-frame having channels in the sides thereof, ofa bead-strip seated within and extendin from each channel, the Walls ofthe channe and the'strip therein being slit and folded to retain thestrip.

4. The combination with a sheet meta'l Window-frame having a channeltherein, of a sectional bead-strip within the channel, one of saidsections and the walls of the channel adjoining it being slit and foldedto hold the 4 5 section within the channel, and a second secwith a sheetmetal end adaptedto be j ect into the aperture and under one end wallanges upon the plate project-- thereof, side 'ing into the aperture, andan end projection upon the plate adapted to overlap and to be secured tothe other end Wall of the aperture.

6. The combination With a sheet-metal- Window-frame, of a parting-stripadapted to be secured thereto and comprising channeled sections, one ofsaid sections having a reduced inserted into the other section.

7. The combination with a Window-frame having partitioned sides formingcom artments, and pulleys within the head 0 the ame, of a sash withinthe frame, a rod slidably mounted therein, fusible means for holdin therod against movement in the sash, balances within the frame andpermanently connected to the sash, a chain connected to the rod andextending over the pulleys into ..one. of the compartments, andan'auxiliary weight suspended in' said compartment by the chain: V

8. The combination with a sheet-metal sash having a top rail formed ofinterlocking metallic strips; of a trough-shaped receptacle in the toprailof the sash and .havin opening in the bottom thereof and through thebottom of the rail, the edges of said receptac'le being permanentlysecured Within the interlocking portions of the rail; and a fusibleclosure for the opening.
